Eibach 1000.188.0145 Race Main Spring ID Midget Legend - 1.88

The Eibach 1000.188.0145 is a high-performance race main spring designed for Midget and Legend racing applications. Featuring a 1.88-inch inner diameter, this precision-engineered spring is part of Eibach's world-renowned ERS (Eibach Race Spring) system, offering exceptional performance and flexibility for suspension tuning.

ERS Double Spring System Technology:

This main spring is designed to work within Eibach's innovative double-spring system, which combines main and tender springs to create a sophisticated two-stage rate configuration. The main spring provides a linear-rate characteristic that determines the final rate of the suspension system. When paired with a tender spring, the system delivers a softer initial rate during combined compression, then transitions to a firmer ending rate once the tender spring fully closes. This precise balance optimizes road contact while controlling body roll, squat, and dive during racing conditions.

Key Features:

• Compatible with over 700 ERS spring components for virtually unlimited suspension combinations
• Linear-rate characteristic for consistent, predictable performance
• High spring travel and deflection capability at short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability for extended component life
• Precision manufacturing with tight tolerances
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number, spring rate, and physical dimensions for easy identification
• Block resistance to prevent coil binding
• Individual protective packaging

Engineered for serious racers and suspension tuners, this Eibach main spring delivers the precise control needed to transform engine power into optimal track adhesion. The spring works seamlessly with Eibach connecting plates, tender springs, and helper springs to create a fully customizable suspension solution.
